Ultra-pure silicon tetrachloride will also be purchased back by Jiangsu Zhongneng Polysilicon for polysilicon production.

The move is part of GCL-Poly's plans to leverage existing facilities and diversify its market footprint and potentially reduce material costs for polysilicon production.

“Dedicated to promoting the application of solar energy worldwide,GCL-Poly is the largest global supplier of photovoltaic materials. This cooperation can combine Evonik’s advanced technologies of producing silica and ultra-pure silicon tetrachloride with Jiangsu Zhongneng’s leading technologies of silicon material production,” said Zhu Gongshan, chairman of GCL-Poly.

“The partnership will enhance GCL-Poly’s overall competitiveness by diversifying the silicon products, better serving its main business, and meeting market demand.”
